Letters Patent No. 65,608, dated June 11, 1867.

IMPROVED METHOD `or' HANGING WINDOW-sten.

T0 ALL WHOM THIS MAYCONCERN:

Beit known that I, WILIJAM ROBERTSON, of Plymouth, in the county of Marshall, and State of Indiana, have invented a new and useful improvement in devices for Hanging VindoW-Sash; and I do, hereby declare that the following is a full, clear, and exact description of the saine, reference beingliad to the accompanying ldrawings and letters of reference, making a part of this specication, in which- Figure is an elevation of my invention as attached to the window-frame.

Figure 2, a perspective representation of one of the pulley-blocks with the pulley in position for use.

The nat-ure of my invention consists in arranging a pulleybloek corresponding with the thickness of the division sto'p, and fitting it into the top of the groove in the jamh-casing, for the purpose of providing a convenient means for hanging the upper and lower sash'of windows, so that their weight willV balance each other. I am well aware that sash have been hung by what is commonly known in many parts of the country as balancing cords; but` as the devices used for'running the cords have been of such a character as to prevent the possibility of taking the sash out of the frame in a convenient manner, as a consequence, this method is not very much in use. I claim, by means of my invention, to have obviated this dilieulty by tting the pulley-4 hlocks into the same groove which support-s the stop, by which means the stop and block can he easily removed 'from the frame, so as to allow the sash to be taken out for the purpose of glazinggtc.

In order to give a correct understanding of my invention, I have marked like parts with like letters, and

will now give a detailed description.

A represents the common window-frame, and B C the sash, all of which are constructed in the usual manner, except the partition stops E, which are made suiIieient-ly short at the top, as seen at D, iig. I, to allor the pulley-blocks F to iit into the grooves shown by dotted lines G{'ig. 1, and practically foi-m a continuation of stops E. This pulley-block F is shown more clearly at iig. 2,'4and has the inclined `fslot a, for the purpose of supporting the shaft c of pulley b. The blo'ck F may be made of east iron, and a little thicker than the stop below, so as to iit int'o groove G tightly, in which case itrwill be very durable and stay in its place.

Operation.

But little skill is required to put my device into practical use. The cords I are simply put overpulleys b in the usual manner, and attached to sash B C., Whenit is required to take out the sash, the stops E must first be removed, and then the blocks F can be drawn out of the grooves G, which will relieve the sash from the frame A.

Having thus fully described my device, States, s

The pulleywhat I claim, and desire to secure by Letters Patent cf the United block F, when constructed and arranged substantially as and for the purpose set forth.

WILLIAM ROBERTSON.
